It includes essential accessories and a robust storage case, making it a must-have for any serious technician. ## Description The Fowler 54-646-401-0 X-Tender-E Electronic Dial Bore Gage Set has a measuring range of 1.4 to 6" and resolution of 0.00005"/.001mm. A minimum hold feature locks on the bore size as this direct-measuring gage is rocked within the part to be measured. The electronic indicator provides both inch or metric readings. A two-point contact system is used to detect geometry problems such as ovality and taper, and carbide-tipped contact points provide extended wear and improved abrasion resistance. The gage is self-centering and includes an extension holder. This product has 1 year warranty offered by Fowler High Precision. If you experience any problem contact Fowler directly for warranty claims. Bore gages measure holes, or bores, in a workpiece. They can measure the interior diameter of a hole at any depth, while internal micrometers can only measure to the depth of their teeth. Bore gages are typically calibrated with a setting ring and come in two types: simple and direct-measuring. Simple bore gages are used with a caliper to transfer the hole measurement, while the more complex gauges take the measurement directly, and display it through a vernier, dial, or digital display. Bore gages have a two- or three-point contact, indicating how many points on the gage head touch the inside of the bore. Two-point contacts are better at measuring ovality, while three-point contacts are used to measure lobing or triangular form error. Pistol-grip bore gages are used for fast, single-handed operation with repeatable results from one operator to another. Bore gages can also be used in special applications, such as measuring threads, spline pitch diameters, and deep bores. Fowler, an American company, manufactures inspection and measurement instruments such as electronic indicators, calipers, bore gages, and micrometers. The company, founded in 1946, is headquartered in Newton, MA. ## Features - Accurate Measurements: The bore gage features an electronic indicator with resolution of 0.00005"/.001mm and measuring depth of 9 inches - Durable Construction: This electronic indicator provides both inch and metric readings; two-point contact system is used to detect geometry problems such as ovality and taper; carbide-tipped contact points provide extended wear and improved abrasion resistance - The easily adjustable bore gage is self-centering and includes a 2-inch contact extension holder - Minimum Hold Feature: This electric gage locks and holds the bore size as the gage is rocked within the part to be measured - Set Includes: A storage case, 2 batteries, 15 measuring anvils, 4 spacers and an instruction manual ## Product Details - **Brand:** Fowler - **Range:** 1.4 - 6" - **Measurement Accuracy:** +/-0.0001 inches - **UPC:** 646795113879 646795153677 - **Set Name:** Set ## Images ![54-646-401-0, X-Tender-E Digital Dial Bore Gage Set with 1.4" - 6"/35mm-150mm Measuring Range - Image 1](https://m.media-amazon.com/images/I/61I5+QAuOxL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by J***E on May 18, 2023* Great product, excellent price, very fast shipping ### ⭐⭐⭐⭐ Good quality tool with repeatable results, instructions are very minimal. *by K***R on May 9, 2021* Not very easy to setup but there is a old video on YouTube on setup and calibration. The included instructions are pretty much useless. The tool itself is good quality and does it's job with repeatable results. A set of snap gauges would do just aswell in my opinion though. ### ⭐⭐⭐⭐⭐ Not for beginners *by K***T on August 29, 2015* If you are just learning it took me some time to figure it out. I couldn't find much help on line for a analog gauge either. You also need some other form of measurment to get your tool into calibration. ## Frequently Bought Together - Fowler 54-646-401-0, X-Tender-E Digital Dial Bore Gage Set with 1.4" - 6"/35mm-150mm Measuring Range - Fowler 54-870-004-0, Xtra-Value Ii Digital Micrometer With 3-4"/75-100MM Measuring Range --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/16842667-54-646-401-0-x-tender-e-digital-dial-bore](https://www.desertcart.sg/products/16842667-54-646-401-0-x-tender-e-digital-dial-bore) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-04-23*
